Northern Colorado Plateau Network, Inventory and Monitoring Program 20080115 vector digital data http://www1.usgs.gov/vip/nabr/nabrgeodata.zip doi:10.5066/F7VX0DHC The plot point displays the 97 field plot and observation points visited in 2003 & 2004 as part of the vegetation mapping project. Sample plots were located subjectively in representative vegetation throughout the park. Field crews decided where and when to use observation points or vegetation plots to sample the vegetation. Vegetation plots were placed in stands judged by field crews to represent legitimate vegetation types that could be classified to the National Vegetation Classification (NVC) system using standard multivariate analysis techniques. Observation points were placed in stands (1) if the vegetation was highly altered and therefore not classifiable, (2) to provide information about the distribution of common vegetation types adequately sampled in vegetation plots, or (3) if the stand represented a unique vegetation type that was too small to hold a 400m2 sample plot (e.g., seeps, Hanging Gardens). The points were originally GPSed (using recreational GPS units), coordinates noted on the field sheets and then typed into the database. The AA point displays the 288 accuracy assessment (AA) points visited in the fall of 2004 as part of the vegetation mapping project. The points were randomly selected, stratified by the map units used for vegetation mapping and further screened so as not to fall on inaccessible isolated mesa tops and vertical canyon walls. The coordinates were uploaded to Garmin hand-held GPS receivers so that ecologists could navigate to them in the field. Some AA points fell on ecotones and two sets of data were recorded on the evenly-split site. AA points that fell along polygon edges sometimes did not represent the entire polygon well and some AA points fell on small patches of vegetation that were different than the community in the larger area. Plots were collected to characterize the vegetation at Natural Bridges National Monument. These points show the location of plot and observation points visited, while accuracy assessment plots were visited to verify the mappers? interpretation of the vegetation communities. The intended use of all data in the park's GIS library is to support diverse park activities including planning, management, maintenance, research, and interpretation. 20030701 20041130 ground condition Complete None planned Natural Bridges National Monument -110.057966 -109.953286 37.648256 37.570602 None Plots Observations Vegetation Field data Accuracy assessment Points National Park Service Theme Category Thesaurus Vegetation ISO 19115 Topic Category biota None Natural Bridges National Monument NABR San Juan County Utah UT Colorado Plateau National Park Service NPS USA National Park System Unit Name Thesaurus Natural Bridges National Monument National Park System Unit Code Thesaurus NABR None Standardized National Vegetation Classification System vegetation classification alliance community association Kingdom Plantae None None Northern Colorado Plateau Network, Inventory and Monitoring Program Janet Coles Vegetation Ecologist mailing

Von Loh, A. Evenden, G. Manis, G. Wakefield. and A. Wight 20080115 report http://science.nature.nps.gov/im/units/ncpn/ Network staff has ground checked and verified all features to the best of their knowledge. GIS personnel verified all features and attributes. There are no duplicate features present (park specials points are duplicates of plots, intentionally). This data contains all the observation, plot points, accuracy assessment points visited for the Natural Bridges Vegetation Mapping Project. This data was collected using recreational grade GPS receivers (generally Garmins). A dop or meters error reading was recorded when applicable. Recreational GPS receivers generally have horizontal errors of 3-15 meters (less than 40 meters). GPS accuracy varies for each plot. Error values were recorded on the plot form. Standard GPS Elevation Error USGS Unknown raster digital data 24,000 CD-ROM unknown publication date DRG Digital Raster Graphics were used for field maps. Field plot data collection was accomplished with the use of recreational GPS units (generally Garmins).
